उत्तर

Devangi buys a chair for ₹ 700 and sells it for ₹ 750. She earns a profit of `underlinebb(7 1/7)` % in the transaction.

Explanation:

Given, CP of chair = ₹ 700

And SP of chair = ₹ 750

We know that, Profit = SP – CP = 750 – 700 = ₹ 50

Also, profit% = `"Profit"/"CP" xx 100% = 50/700 xx 100% = 7 1/7%`

Hence, the profit earned by Devangi is `7 1/7%`.
